# Project Progress An overview of Pytra's development status. Links to test results, tasks, changelog, and documentation. ## Frontend (shared pipeline) [How EAST works](../guide/east-overview.md) — A guide that walks through how Python code is transformed through EAST1 → EAST2 → EAST3 with concrete examples. For first-time readers. [How emitters work](../guide/emitter-overview.md) — A guide showing how EAST3 is converted to C++/Go/Rust etc., with before/after comparisons. [EAST spec](../spec/spec-east.md) / [EAST1](../spec/spec-east1.md) / [EAST2](../spec/spec-east2.md) / [EAST3 Optimizer](../spec/spec-east3-optimizer.md) / [Linker](../spec/spec-linker.md) — Formal specifications for each stage. ## Backend support [Overall summary](./backend-progress-summary.md) — Overview of fixture / sample / stdlib / selfhost / emitter lint for all languages in one page. [Parity changelog](./changelog.md) — Auto-recorded log of when PASS counts increase or decrease. Use this to catch regressions immediately. Details: - [fixture](./backend-progress-fixture.md) — language feature unit tests - [sample](./backend-progress-sample.md) — real applications ([samples list](../tutorial/samples.md)) - [stdlib](./backend-progress-stdlib.md) — Python standard library compatible modules - [emitter host](./backend-progress-emitter-host.md) — can each language host the C++ emitter? (intermediate milestone) - [selfhost](./backend-progress-selfhost.md) — transpile the compiler itself. Requires fixture + sample + stdlib all PASS - [emitter lint](./emitter-hardcode-lint.md) — emitter hardcode violation detection — Counts grep-detected violations where emitters hardcode module names, runtime symbols, or class names instead of using EAST3 data. ## Task list [TODO index](../todo/index.md) — Tasks managed per area (C++ / Go / Rust / TS / infra). Each agent reads and writes only its own area file. ## Changelog [Detailed changelog](../changelog.md) — Daily record of changes including spec updates, new features, bug fixes, and documentation. ## Documentation - [Tutorial](../tutorial/README.md) - [Guides](../guide/README.md) - [Specification](../spec/index.md)
